Mock Location Automator

Enabling mock locations for LocationManager and FusedLocationProvider before running any Android instrumentation tests.

It providers a Junit-rule to grant needed permissions by executing adb commands and setting mock mode enabled for different location providers.

Example

@RunWith(AndroidJUnit4::class)
@LargeTest
class YourScenarioTest {

    @get:Rule
    val mockLocationRule = MockLocationRule()
    
    @Test
    fun test_scenario_x() {
        // ...
        mockLocation(latitude, longitude)
        // ...
    }
}

Usage

Apply MockLocationRule

In order to use this library, you must add MockLocationRule into your test class.

This rule do the following steps:

1. Add test apk to Settings > Developer Options > Select Mock location app, So all mock locations can be applied from test classes.
2. Grant android.permission.ACCESS_FINE_LOCATION and android.permission.ACCESS_COARSE_LOCATION to avoid any permission errors.

Mock a single point

You can mock a location by calling mockLocation method. To avoid jumping back to the real position, It will preserve it periodically.

If you don't want this behaviour, you can simply disable preserving mode:

mockLocation(latitude = 12.45, longitude = 56.78, preserve = false)

Mock multiple points

You can also mock multiple locations by passing a list of DelayedLocation. It will mock each location after a deplay which specified in the DelayedLocation.

Here is an example:

mockLocations(
    listOf(
        DelayedLocation(location1, 1000),
        DelayedLocation(location2, 2000),
        DelayedLocation(location3, 3000)
   )
)

So after the execution of this method, location1 will be applied after 1 second, then 3 seconds (1+2) later locations2 will be applied and so on.
